Camino Inca

English: Among the many roads and trails constructed in pre-columbian South America, the Inca road system of Peru was the most extensive. Traversing the Andes mountains and reaching heights of over 5,000 m (16,500 feet) above sea level, the trails connected the regions of the Inca empire from the northern provincial capital in Quito, Ecuador past the modern city of Santiago, Chile in the south. The Inca road system covered approximately 22,530 km (14,000 mi) and provided access to over three million km² of territory.
By far the most popular of the Inca trails for trekking is the Capaq Nan trail, which leads from the city of Cusco to Machu Picchu, the so-called "Lost City of the Incas".
